strong acid.

3.

What are solutions that are resistant to large changes in pH?


electrolytes
strong acids
buffers
strong bases

4.
Which of the following are examples of strong electrolytes?

strong and weak bases
strong acids and strong

Answer 1

weak acids and weak bases
pure water and buffers



Please Help

Answer 2

I give you some relations and you can then answer the questions your self:

1) pH = - log[H3O+]

2) The right thing would be to say pKa due to the fact that pH is used to describe the acdity of a solution, while pKa is characteristic of a particular compound. However we say the following:
pH > 7 -> basic solutions
pH < 7 -> acdic solutions.

3) A weak acid and its coreresponding base that is near the same concentration are resistant to large changes in pH.

4) a strong electrolyte is a specie that would compleately dissociate or ironize in a solution.
